Pull request overview

This PR adjusts the Overkiz cover entity’s is_closed reporting so that when the upstream device state is "unknown", Home Assistant exposes is_closed as None (unknown) rather than incorrectly implying an open/closed boolean.

Changes:

• Update OverkizCover.is_closed to return None when the device reports OpenClosedUnknownState == "unknown".
• Extend the Overkiz test fixture set with a garage door device that reports "unknown".
• Add a snapshot assertion covering the new entity and the expected is_closed: None attribute.
